DISH-WASHING MACHINE.

Specification of Letters Patent.

Patented Ma 24,1910.

Application filed March 13, 1908. Serial No. 420,799.

To all whom it may concern:

Be it known that I, JOHN G. KNAPP, a

citizen of the United States, residing at Boonvill'e, in the countyofUneida and State of New York, have invented certain new and usefulImprovements in Dish- VVashing Machines, of which the following is aspecification, reference being had therein to the accompanying drawing.

My invention relates to an improved dishwashing machine, and I declarethe following is a full, clear, concise aiid exact description thereof,sutlicient to enable one skilled in the art to make and use the same,reference being had to theaccompanying drawings in which like lettersrefer to like' parts throughout. i k A feature of the device is infthemeans provided for placing and; removing the dishes, the "character ofthei motion of the device and the resulting action. of the water and therinsing tank. I 3 H Other features will appearin the specification's anddrawings. 1 r Y I Figure 1 is aside View of the machine ,sliowiiig partof the outline ofthe innerv member byv dotted lines. Fig. 2 is a sideview in section on substantially the center line'showing a form ofoperating means.

Fig. 3 is a View partially in cross section to show part of theoperating mechanism.

Fig. 4 is a like view showing another form. of operating mechanism."Fig. 5 is a top viei.

'Referring to the drawings in detail. the machine comprises a stationarytank A, water tight, with drainage outlet a. Within the tankA is swung atilting tank B mount- .ed' relatively near the top by trunnioiis Z) onthe fixed tank A. The tank B is of a size to swingfi-eely in tank A, theends a'lternatcly rising and falling. The tank B has its bottom slopingdownward from the ends as seen in Fig. 2 and has drain-hole 6 near thecenter. Within the tankB is a water-tightbox or rinsing tank C withdrainage c, the box being, formed with sides 0, a connected to the sidesof thetank B and .a bottom c ahove the bottom of the tank so that waterin the tank flows free from one end to the other when the tank istilted. V The tilting of tank B isefi'ected by any suitable means, twoexamples of which are indicated. In the style shown in Fig. 4, D,-

is a depending loop on the bottom of-the tank and a'crank shaft Eprovided with a crank arm is mounted in the tank A, the crankrarmengaging the loop D so that the oscillation of the shaft by means ofthelever F swings the tank B in its trunnions and tilts either end up.In Figs. Qand 3 there is. the loop D, substantially'as before, the shaftE being supported in the wall of tank A and in a bracket G suitablymounted. 165 iAt -the inner end of the shaftis pitinan iwheel G with pin5/, in the loop. The shaft lhas suitable gear members illustrated by Hand H to which power is applied by belt or othersuitable meansillustrated by .ihandle Lgto" revolve the shaft and tiltthe tank B ilt ais a swinging clip to engagiileveniEingiven position, to hold'the tankin place. This will represent any means suitable for locking thetank inplace for loading or unloading.

In operation the dishes are placed in basket J ,one in each endcompartment of the tankB if desired, supported on clips 7) and on thebottom of the tank. lVater being put in the tank, the mechanism is setin motion to tilt the tank when the water rushes from one end to theother, some pouring up from beneath box. C and some rushing to the endof thetank and there.turned baek ontothe dishes. To prevent splashingwhen one of the compartments is empty, covers K are provided to inclose,more or less, the end compartments. When the action of the rushing waterhas cleaned the dishes the 0 basket is lifted out and the dishes rinsedin the water of tank mgbox and then placed on outwardly swinging shelfL, mounted by strip Z on tank A and having outlet Z connected to tank A.I

Having described my invention, what I claim as new and desire to secureby Letters Patent, is:

1. A. inachinc of the character described comprising a tank, atiltingtankmounted therein having two interior partitions with a bottomconnected thereto and spaced above the bottom of the tilting tank, meanson said partitions for supporting (in. conjui'iction with tllflbOttOlHof the tilting tank) di sh receptacles' substantially on a level, andmeans foroscillatiiig the 'tiltin tank to and fro, substantially as(lGSCIlbEHf 2. In a machine of the character described, the combinationof a main tank and a. secondarytank pivotally mounted therein and hav ngpartitions fixed therein whereby to form an inner receptacle and outerreceptacles in the secondary tank, the former or mner receptacle beingspaced above the bottom of the main tank with a passage tl'ierebetween,and means for sup porting in the secondary tank, substantially asdescribed.

f 3. A machine of the character described comprising a tank, a tiltingtank mounted therein having two interior partitions with a bottomconnected thereto and spaced above the bottom of the tilting tank, andmeans for oscillating the tilting tank to and fro, substantially asdescribed.

4. In a device of the character described, a pivotally mounted Washingtank having the bottom dish-carriers in the outer receptacles ingtankthe sameis tilted to and fro.

In testimony whereof I affix my signature in presence of two witnesses.JOHN G. KNAPP.
